Title: Magnetic disk substrate
Inventor: NAKAO MASAYUKI
IPC: G11B5/66
Filed: 1985-01-29
Abstract: PURPOSE:To obtain a magnetic recording medium which obviates output dropout by consisting said medium of a substrate made of metallic aluminum or the alloy thereof, substratum film provided on the substrate and thin magnetic film deposited by evaporation on the substratum film and forming the substratum film of an anodically oxidized film and non-magnetic material deposited by plating to the etch pits of the anodically oxidized film. CONSTITUTION:The anodically oxidized film is recessed and is slightly thin in the parts where there are the etch pits. The non-magnetic material is preferentially plated to the recesses made on the etch pits if said material is plated onto such anodized surface of the aluminum sheet. The plating is ceased where the plating layer grows to about the thickness at which the etch pits are filled. The plated part is thoroughly washed to wash away the chemical and the plated sheet is dried. The plated layer is polished until the plated part is made flush with the alumite layer. Metal is preferable as the non-magnetic material to be plated, for which copper, zinc, etc. are usable. Copper has a good plating characteristic and is therefore more particularly preferable. A thin film of Fe3O4 or Co-Ni-(N) is formed thereon by sputtering and is subjected to a heat treatment, by which the magnetic medium film consisting of gamma-Fe2O3 or Co-Ni is obtd.

Title: Sealing resin composition
Inventor: KOKUBO MASANORI
IPC: C08L63/00
Filed: 1989-01-27
Abstract: PURPOSE:To obtain a sealing resin composition excellent in humidity resistance and soldering resistance by mixing a condensate of a polyalkoxyorganosilicone with an epoxy resin with a condensate of a polyalkoxyorganosilicone with a novolac phenolic resin and a silica powder. CONSTITUTION:A silica powder is added to a mixture of a polyalkoxyorganosilicone having a substituent reactive with an epoxy group with an epoxy resin and a mixture of a polyalkoxyorganosilicone having a substituent reactive with a phenolic OH group with a novolac phenolic resin in such a amounts that the silica powder amounts to 65-85wt.% of the entire resin composition. A semiconductor device sealed with a conventional resin comprising an epoxy resin, a novolac phenolic resin and a silica powder has a drawback that the humidity resistance is lowered when it is immersed in a soldering bath. The sealing resin composition of this invention has good adhesion, so that it is scarcely affected by moisture absorption, excels in humidity resistance after being immersed in a soldering bath and can markedly decrease the occurrence of disconnection due to the corrosion of electrodes and a leak current due to water.

Filed: 1994-02-10
Abstract: PURPOSE:To provide the constant current circuit which has excellent temperature characteristics without being affected by hFE of a transistor(TR). CONSTITUTION:The constant current circuit which allows the currents I1 and I2 from a current mirror circuit 1 to flow through a current mirror circuit 2 inhibits the former base current from being sent directly to the latter, namely, is constituted by connecting a diode-connected TR Q6 which sends out the base current to a TR Q7 other than TRs Q3 and Q4 constituting the current mirror circuit 2. Consequently, the influence of the hFE of the respective TRs on the constant currents I is substantially removed, which is evident when an NPN TR is used as the TR Q7. Further, an actuation circuit which operates in power-ON operation to securely send the base current of the current mirror circuit 1 is added.

IPC: H04N9/64
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To conduct level compression of a color video signal or gradation conversion of the signal without causing a change in hue. SOLUTION: A luminance conversion computing element 111 multiplies a gain kw of luminance to each of red, green and blue color signals to conduct arithmetic operation such as knee compression and gradation conversion. In this luminance conversion arithmetic operation, the hue and saturation of a color video signal represented by the red, green and blue color signals are preserved. Furthermore, the red, green and blue color signals outputted from the computing element 111 are fed to a saturation conversion computing element 112 and a gain kc of the saturation and a luminance Wi fed from a controller 124 are used to conduct saturation conversion.  In this saturation conversion, when a maximum level of at least one color signal among the red, green and blue color signals outputted from the computing element 111 exceeds a prescribed level, while the hue and luminance of the color video signal represented by the red, green and blue color signals are made constant, the level of the red, green and blue color signals is converted so that the maximum level of at least one color signal is coincident with a prescribed level.

Consequently, the difference of voltages applied to both ends of the circuit 6 is zero. Thus, the dynamic range of an amplifier circuit constituting the network 5 can be set up to a sufficiently large value, the amplifier circuit can be driven without distortion and side tone balancing state can be stably maintained.
